CoreOS is designed to deliver high-density compute resources. The best way to take advantage of this concept on a small scale is run a personal utility cluster (or single machine) to run various utilities like IRC bouncers and the handful of websites that you inevitably end up hosting. CoreOS is a small, efficient operating system, which means you get more bang for your buck even on small cloud instances.

This etcd release, v0.1.2, is putting some final polish on the 0.1 series of releases. The big feature is a new dashboard designed to visualize the latency of the followers in the network and give you the ability to browse and edit the keyspace. Checkout this Youtube video for details.

There have been a lot of requests from all of you about running CoreOS on physical gear. You want to use all of the features of CoreOS like atomic system upgrades, distributed configuration and Docker containers with the increased speed, flexibility and simplicity of bare metal. It makes a lot of sense to us too and we have been working to get the pieces in place for you to get CoreOS on your bare metal.

We just uploaded images for OpenStack, VMware and KVM to make it easy for more of you to be involved in the CoreOS developer alpha. These images come fresh from our build system and we would love your feedback on what is working and what isn't.

Today we would like to announce etcd, a highly available key value store for shared configuration data. CoreOS built etcd to solve the problem of shared configuration and service discovery. etcd is inspired by projects like Zookeeper, or doozer, but is a completely new piece of software. Some of the key design features:

System upgrades can introduce problems, and when upgrades go bad, manual steps need to be taken to get machines back up. The problem is compounded on public cloud infrastructure since you often have large numbers of machines, and getting to a recovery console can take a while.
